Bottles containing C_(6)H_(5)I and C_(6)H_(5)-CH_(2)I lost their original lables. They were labelled A and B for festing. A and B were separately taken in a test tube and boiled with NaOH solution. The end solution in each tube was made acidic with dilute HNO_(3) and then some AgNO_(3) solution was added. Substance B gave a yellow precipitate. Which one of the following statements is true for this experiment.

Acetic acid tends to form dimer due to formation of intermolcular hydrogen bonding. 2CH_(2)COOHhArr(CH_(3)COOH)_(2) The equilibrium constant for this reaction is 1.5xx10^(2)M^(-1) in benzene solution and 3.6xx10^(-2) in water. In benzene, monomer does not dissociate but it water, monomer dissociation simultaneously with acid dissociation constant 2.0xx10^(-5) M. Dimer does not dissociate in benzene as well as water. The molar ratio of dimer to monmer for 0.1M acetic acid in water (neglecting the dissciation of acetic acid in water ) is equal to :
